Tools & Capabilities Breakdown

Retro Diffusion Pixel Art Tools (20)

create_inference

Generate images, animations (GIF/sprite sheet), or tilesets. Returns hosted URLs and a recovery `request_id`; prefer RD Pro styles for top quality

get_inference_result

Recover or refresh signed output URLs for a successful synchronous generation without generating or charging again

start_inference_job

Start generation as an async job — recommended for animations and batches

get_inference_job

Poll an async job for status and results

list_inference_jobs

List your recent async jobs — recover a `task_id` after a lost submission response instead of re-submitting and double-charging
